Question

How terpenes makes the peel of lanzones as a mosquito repellant?

Answer 1

Lanzone, Lansium domesticum onoceranoid triterpenes (iso-onoceratriene, 3-keto-22-hydroxyonoceradiene, onoceradienedione, lansiolic acid and lansiolic acid A) show significant mosquito repelling and antifeedant activity.

The fruit peel of Lansium domesticum, var. pubescens ( thicker than that one of the sweeter var. domesticum ) exudes a white sap/latex containing the mosquito repelling triterpenes. The dried peel is burned and produces an aromatic, white smoke ( white from the sap and some remaining water ).
